IMPROVEMENT IN WIN DMILLS.

The Schedule referred to in these Letters Patent and making girl: of thesame.

To all whom it may concernea known that I, SAMUELM. ABBOTT, of Wil- ,m ington, in-the county of Will and State of Illinois,

and 3'1 Figure 2 is a side elevation of the same.

' The nature oi my invention consists in the construction and arrangement of a wind-power and mode of controlling. thewind-wheel, as will be hereafter fully set forth.

. In order to enable others skilled in the art to which my' invention appertains to makeaud use the same, I will now proceed to describe its construction and op erat-ion.

A represents the wind-wheel, constructed in any suitable manner, with stationary wings.

' B is the tail,rndder, or vane, which holds the wheel to .the wind.

This .vane is, by a rod, a, (chain, gearing, or other means may be substituted,) connected with another vane or rudder, O, which is smaller than the vane B, and stands at right angles with it, as shown.

D is a wind-disk attached to-the upper end of a lever, b, the lowerend of which slides on the wheelshaft, and is connected with an elbow, d, pivoted on the turntable.

The wind-disk D is, by a rod,-e, connected with the vane G. I

The vanes B O 'areso arranged as to turn onequarter round on their axles.

A weight,- E, is attached to the rod f, on the inner end-ot'the elbow d, to keep the wind-disk-D at a perpendicular in; an ordinary wind, and to allow the disk, with its lever, to fall back before a stifi wind, and so turn the'wheel to a greater. or lesser angle, according to the force of the wind,

. The longer one, B, which was perpendicular and held Lfi'Eigure l of the drawing is mywindmillin plan view, I

the wheel in the wind, changes to a horizontal position the other, 0, which was horizontal, changes to aperpendicular position, takes effect in the wind, and brings the wheel to a right angle, to the position it was in before the disk was blown back. This quarterrevolution of the whole structure above brings the thickness of the wheel into the eye of the wind, and it immediately ceases to revolve. The wheel is kept in this position by-the wind-disk D being placed diagonal to the face of the wheel so long as the gale continues.

As soon as the wind lulls the weight Edraws the disk and lever to a perpendicular, the vanes changing their positions to what they were at first. This brings the wheel into the wind and it begins to revolve again.

I make the space between the bearings of the shaft of the wheel a trough or reservoir for oil to lubricate those bearings, and also the contiguous surfaces of the turn-table or staple or thimble which holds the wheel and vanes in their place.

- I use also a small oil-fountain on the top of. the pitman or perpendicular shaft to lubricate the other rubbing" surfaces. These two oil-fouuts' make it easy to keep the machine well lubricated.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The rudders or vanes B O, placed at right angles of turning one-quarter around on their axles, and connected together by any suitable means, substantially as and for the purposes herein set forth.

2. In combination with the vanes B G, the winddisk I), pivoted lever b, conuecting-rod e, substantially as and for the purposes herein set forth.

3. In combination'with the wind-disk D andlevcr 1), operating the vanes B O, as described, the elbow d, rod f; and weight E, substantially as and for the purposes hcrein set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

SAMUEL M. ABBOTT.
